Title: Drilling tool angle inclination indicator - has drill collar device which is hollow for mud flow path which creates sensed output
Inventor: CLAYCOMB JACKSON REYNOLDS
IPC: E21B47/022
Filed: 1979-09-10
Abstract: The tool incorporates an outer shell which is connected in a drill string above the drill bit and among the drill collars. The device utilises mud pressure variations to pump oil with a piston to energise a closed hydraulic circuit. The oil is delivered via a distribution and manifold system to first fill and scan five hydraulic signals sequentially. The sequential scan of the five hydraulic signals is conveyed to an output mechanism comprising a choke which is placed in the lower end of the tool. The choke varies the mud throughout and thus upstream pressure in the mud circuit, forming an output which can be detected at the surface.

Title: Adjustable stop for vehicle accelerator pedal - comprises electromagnetic ferrite whose force is controlled from rheostat on dashboard
IPC: B60K26/02
Filed: 1979-11-13
Abstract: Two opposing magnetic strips articulate about a point under the accelerator pedal to which one blade is connected by an articulating joint. A stop comprises a magnetic bar on a support attached to the upper strip and which carries a magnetic ferrite which adheres to the lower strip. The ferrite is an electro magnet controlled via a rheostat to control the force required to maintain it on the strip and thus the pedal position at which it is effective. When pedal pressure increases, the magnetic system ceases to oppose insofar as the magnetic field strength decreases inversely with the square of the pedal distance travelled, thus allowing the accelerator to reposess its entire freedom of movement. In the universe situation, the magnetic field automatically re-locks onto the pedal mechanism.
